Some things in the rig people run into issues with them
Such as setting config.
in a quick spot test in the rig .set doesn’t work for me either.
A lot of people have this problem in the rig. Generally I don’t use the rig unless I’m spot testing (mobile) views real quick. And do all my testing on the live site.
So you’ve got as far as you can in the rig. And config setting jsut doesn’t work from a view.
Rig is just there as an approximation, (and can you test video extensions without being live). The rig is also a little out of date with recent changes too. But people have had issues with config setting since time immomorial
